The goal of the studies was to determine hydrological, chemical parameters of water and to examine floristic composition of vegetation of anthropogenic wetlands formed in abandoned excavation pits. For research two objects of different origin were selected: "Porȩba"- mire formed as a result of lignite exploitation and "Bory" former open pit sand mine, both situated in the Silesian Upland (southern Poland). In investigated objects hydrographic mapping and hydrochemical study was performed. In total 22 phytosociological relevés and according to modified Braun-Blanquet method in plots of 9-16 m2 were taken. Vegetation relevés were subjectively placed on, well-hydrated and well-developed and homogenous parts of mires.

In the case of the wetlands Szczakowa and Kotlarnia, water is supplied mainly through infiltration from rivers. In the case of the wetland Szczakowa these are waters of the River Biała Przemsza. This river is contaminated as it receives mine waters from zinc-lead ore mines. Besides high concentrations of heavy metals, these waters show high hardness, which results from the high concentration of ions (Ca2+), (Mg2+) and (SO42-). Therefore, the water of the wetland Szczakowa is sulphate-bicarbonate- calcium-magnesium (SO42--HCO3--Ca2+-Mg2+). The wetland Kotlarnia is supplied by the River Bierawka's water, which also shows a high level of contamination. This is because the river is a receiver of mine waters from coal mines. These waters have high hardness, as well as high concentrations of chloride (Cl-) and sodium (Na2+) ions. Therefore, the water of the wetland Kotlarnia, in its northern section, is of chloride-sodium (Cl--Na2+) type.
